WaterLegacy Resources: Fact Sheets and More

We work hard to keep you informed about the implications of sulfide mining on economics, natural resources, and public health. We continually update our research to ensure that the information on our website is accurate and current. We invite you to read, copy and post, print, or otherwise share the facts with your communities, especially those who stand to be most directly affected by the proposed new mining for copper, nickel, and other metals in sulfur-bearing rock. Please download our fact sheets and share them with your family, friends, and neighbors.

Sulfide Mining Fact Sheets

  • PolyMet Impacts on Environmental Justice, Human Health & Climate Resilience Fact Sheet – Find out how PolyMet’s centuries of waste and pollution and its proposed location in sensitive wetlands and tribal Ceded Territories would result in threats to human health from mercury contamination of fish, disproportionate impacts on environmental justice communities, and massive climate change harm.
  • WaterLegacy and Sulfide Mining Fact Sheet – Describes WaterLegacy’s mission, outlines its unique and award-winning advocacy and provides important information on the sulfide mining and the PolyMet project - Minnesota’s first proposed copper-nickel mine.

  • Protecting Minnesota’s Wild Rice from Sulfate Pollution Fact Sheet - Learn about the importance of Minnesota wild rice, the laws adopted to regulate sulfate pollution, and the undue influence of the mining industry in opposing sulfate pollution controls. Learn how you can Take Action to protect wild rice, clean water and science-based environmental laws.

  • PolyMet and Glencore Fact Sheet – Describes PolyMet’s close partnership with Glencore, a notorious multinational corporation ranked among the world’s worst due to environmental and human rights violations. Explains PolyMet’s dependence on Glencore for financing and Glencore’s management influence and right to purchase PolyMet production.

  • Health Effects Fact Sheet -- Across Minnesota, doctors, nurses and citizens are requesting that the Minnesota Department of Health (MDH) analyze adverse health effects and consider public health before the PolyMet NorthMet open-pit copper-nickel mine project proceeds to any permitting process. Learn and share why an assessment of human health effects is needed.

  • PolyMet Water Resources Fact Sheet -- Find out how waste from PolyMet's proposed open pit sulfide mine and waste dumps threaten Minnesota's clean water, public health, and natural resources.

  • PolyMet Long-Term Treatment Fact Sheet -- See how the wording about long term water treatment in PolyMet's Mine Plan was changed through various drafts in order to minimize the problem.
  • Economic Fact Sheet -- Learn  the real economic benefits and risks of sulfide mining to Northeastern Minnesota and some unexpected facts about the PolyMet sulfide mine proposal.

  • Recycling Fact Sheet -- Did you know that recycling can provide the U.S. with the copper and nickel we need for cellphones and other technology — with less impact to the environment? Learn more here.

  • Wild Rice Sulfate Facts -- Sulfide mining also threatens natural wild rice. WaterLegacy intervened in a lawsuit filed by the mining industry to strike down the sulfate pollution standard that protects natural wild rice. We won our case and preserved the standard in district court and at the Minnesota Court of Appeals. Learn more about the wild rice standard and why the standard is critical to limit sulfide mining pollution, protect natural wild rice, and prevent brain damage to infants and children resulting from bioaccumulation of methylmercury in fish.

  • Wild Rice Rulemaking Fact Sheet -- Reviews laws that govern wild rice rulemaking and explains why "waters used for the production of wild rice” should include all existing wild rice waters identified by the Department of Natural Resources or tribal research as wild rice waters and any waters growing natural wild rice at any time covered under the Clean Water Act (1975 through today).

WaterLegacy needs volunteers. Please contact our Communications Coordinator - jessica@waterlegacy.org - if you would like to volunteer or help plan an event to reach out to members of your community and help them learn more about sulfide mining, particularly the proposed PolyMet NorthMet sulfide mine and its waste dumps.
